You can buy a power adapter to plug into your wall outlet and hook the power commander to it, then your desktop. It needs power in order to program, normally hooked up to the bike with the ignition on to program.
As for a map for the D&D, I didn't see one available on the power commander web site, but you can try the different maps to see if one is close. Or take it to your dealer and have a custom map made.
